Hello,
I'm working with a PXIe-1062q Chasis and a PXIe-4461 ADC. I'm trying to sample a senoidal signal.
In Labview I9m using an example VI call "Continuos Output.vi". In this VI i'm having problems when i want to configure the reference clock, in the option "Timing Settings"
When I use the 4461 with his own board clock, the option "OnBoard Clock", the sampling it´s ok. But when I change for any option, for example "PXI_Clk10" (that's the clock of the backplane), ocurrs an error that I can't understand and I can't find in the NI page.
In the NI MAX the chasis and the 4461 are ok.
Thanks for your help, regards from Argentina.

santo_13, thank you very much for your response.
I've made the changes that you proposed to me. I've received the following error
I would appreciate if you send your ideas about the causes of this problem.

Just based on the 'SourceDevice' field, I assume that you've installed the 4461 on slot2 which is PXI only.
In this case, the reference clock has to be 'PXI_CLK10' and clk rate be 10MHz.

It works! I'll change the ADC to the slot 5 and I'll probe the Pxie_Clk100 chasis reference. Thanks for the help!!!
I ask you one more question:
How can i set up the reference clock in the DAQ PXIe-6733? I have this device en the same PXI Chasis than the 6674t and the 4461.
I saw in the manual that i have to use the RTSI bus. In that case, the pag 14 of the 6733 manual says that the RTSI Clock is the PXI trigger (7) bus.
So, when i try to route the PXI_Clk10 to the PXI_Trig7 (or another PXI_Trig line occurs an error)
And when I try to set up the time reference of the 6733 in labview occurs other error:
Could you help me with this?
Thank you very much!

Firstly, santo_13 your help was very important. Thank you very much!
The question that I've written in this chat was solved.
Besides, i I've writen another question about the synchronization of the PXIe-6733. I've found the answer in that post
